Hey,
Paid a visit today to the trafford centre and VERY nearly ended up walking away with a Tamron 17-50 VC 2.8 lens for my 40D.
I gave myself 20 minutes to *think* about it - in which time I googled as many reviews on the lens as I could on my iPhone and read enough to put myself off.. but since then I have got home and been doing some googling and thinking about it, and its got me wondering this:
Q) Most of the reviews I read on this lens say it is slightly soft, especially around the edges when used at F2.8, but this improves from F4 onwards.
I then found a review which had sample pictures at various F settings, and I downloaded these in full resolution format. I then set to work in Photoshop on the F2.8 image and applied a Unsharp Mark of 10 with a 250 radius and was very impressed by the result....
F2.8 No PP done

F2.8 Unsharp Mark of 10 x 250radius applied, no other PP

To me, the image once PP'd looks fantastic! Im very impressed!
So my real question is - If by setting a batch process function in Lightroom of sharpen + X% which I then apply to all images taken with this lens, do you think it would be a good idea?
IS/VC/OS is a must for me.... and the 2.8 aperture is VERY attractive as a lot of my photos are done in low light. I had been looking at the Canon 17-55 IS which costs a small fortune... Ok fair enough IQ may be better with the Canon lens.... but for the sake of a 1second batch processing function when importing images in Lightroom to massively improve the IQ of photos would the Tamron 17-50 F2.8 VC lens not be a good choice?
The price of the Tamron is around the £330 mark vs the Canon 17-55 2.8 being £800
Im not a pro photographer and although I love taking good quality pictures am I really going to see the difference between the 2 lenses (after PP'ing the Tamron) especially as the largest I print is around 20"x16".
Thanks for any help/advice
